AUGUST 0. JOHNS-ON, OF CHICAGO, ILLINOIS.v

WINDOW-SASH.

To all 'whom it may concern Be it known that I, AUGUST O. JOHNSON, asubject of the King of Norway, residing at Chicago, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in VVindow-Sashes; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in window sashes and moreparticularly to those being provided with means for readily detachingthe panes of glass therefrom.

The primary object of the invention is to provide a sash of thischaracter so constructed as to obviate the necessity of using putty tosecure the window panes in place.

A secondary object is to provide a sash of this character which will besimple, strong and neat in appearance, and which will effectuallyexclude the most severe weather.

Vith these objects in view, the invention resides in certain novelfeatures of construction and combination herein described and claimed,and shown in the drawings wherein- Figure 1 is an inner side view of asash constructed in accordance with my invention. Fig. 2 is an outerside view thereof. Figs. 3 and 4 are horizontal sectional views on thelines 3-3 and 4 4 of Fig. 1. Fig. 5 is a detail side elevation of aportion of the sash showing the manner in which the pane carrying framesare secured in the frame of the sash; and Fig. 6 is a detail of one ofthe pane securing bars.

In the drawings I have shown my improved window sash as comprising aframe 1 of suitable construction, a removable window pane 2, and a paneretaining frame 3 removable with said pane.

Secured within the opening of the frame 1 in any suitable manner, suchas by screws 4, is a metal strip 5 which extends on all four sides ofsaid opening and has its outer edge bent inwardly to form a channel 6.This channel is partially filled with a packing 7, of felt or othersuitable material, for a purpose to appear.

The pane retaining frame 3 is shown as constructed of angle iron bars 8within the angle of which the pane 2 is adapted to seat.

A second frame 9 comprising angle bars Specification of Letters Patent.

Application filed November 20, 1913.

Patented July 14, 1914.

Serial No. 802,095.

9 overlies the pane 2 and seats within the outwardly projecting flangeof the bars 8 and fastening screws l() are then passed through theoutwardly projecting flanges of the frames 3 and 9 and threaded intoreinforcing strips 11. The above-mentioned flanges of the frame 9 arepreferably notched as at 12 for the reception of the screws 10 wherebythe bars 9 may be moved closer to or farther from the frame 3 for theaccommodation of panes of different thickness.

In order to removably secure the outwardly projecting flanges of theframes 3 and 9 and the strip 11 within the channel 6 and in contact withthe packing 7 therein, I form the strip 5 with oppositely disposed slots13 in which cam noses 14 of pivoted latches 15 carried by the frame 3are adapted to project. I also provide the frame 3 with knobs 1G at 'itsupper and lower ends for facilitating the removal of said frame and itscoacting parts.

Although I have described my invention with considerable minuteness I donot wish to be limited to details other than those pointed out in theappended claim, and it will be .obvious that although I have shown myinvention constructed for application to an ordinary window frame, itmay be inserted within a sash of common construction by making necessaryalterations.

Vhat is claimed as new is:

A window sash comprising: a frame, an inwardly extending channeledflange secured within the opening thereof, packing in the channel ofsaid flange, an angle iron frame, a window pane seated within the anglethereof, a second angle iron frame resting within said first mentionedangle iron frame and in contact with said pane, a reinforcing stripseated within the angle of said second mentioned angle iron frame,screws passing through said angle iron frames and into said reinforcingstrip, and means for retaining the outwardly projecting flanges of saidangle iron frames and said reinforcing strip seated within said channeland in contact with said packing.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
